NICHOLAS DOVAS, OF NEW YORK, N. Y.

LID-SUPPORTER.

Specification of Letters Patent.

Patented June 1, 1920.

Application filed January 19, 1920. Serial No. 352,298.

To all whom it may concern:

Be it known that I, NICHOLAS A. DovAs, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Lid-Supporters, of which the following is a specification.

This invention relates to lid supporters.

Some of the objects of the invention are: to produce a comparatively inexpensive device of this character with which the lid of any object may be effectively sustained in various or different open positions; to produce a device which embodies a pair of elements, which co-act to sustain the lid of an object in various or different open positions in virtue of the impingement of certain parts of one of said elements against certain parts of the other of said elements-- the said element being responsive to the movements of the lid to circumvent the impinging action to permit the lid to be moved to a closed position. With these and other objects in view the invention resides in the simplification of a device of this character and in the particular provision and arrangement of parts hereinafter more fully described and illustrated in the accompanying drawings in which Figure 1 is a sectional elevation illustrating the application of the present invention.

-Fig. 2 is a similar view showing the positions, the several parts of the device, as sume when the lid is in open position.

Fig. 3 is a detail view illustrating the manner in which one of the co-acting elements of the device is moved to a predetermined position and the manner in which it is sustained in such position to permit the lowering of the lid to a closed position.

Fig. 4 is a detail view illustrating one of the features of the device.

Fig. 5 is a modified form of the invention.

Referring now to the drawing, it will be seen, that there has been shown so muchof an object only, which represents one part thereof and another part which represents the lid therefor. It is to be understood that the device is not'to be limited to its use to any particular lidded object but that the same may be used upon all kinds oflidded objects. I

In the drawing 10 designates one part of an object and 11 its lid which is hinged thereto as at 12. A plate 13 is secured to the part 10 in any suitable manner and an element 14 is pivotally secured to the plate 13. The element 14 is provided with an aperture 15. An element 16 is carried by the lid 11, and is pivoted as at 17, to an attaching member 18 secured to the lid 11, as shown in the drawing, or in any suitable manner. The element 1.6 is disposed to extend through, and is, at times movable through the aperture in the element 14. The aperture 15 has dimensions slightly larger than the cross section dimensionsin a plane at a right angle to the side edges-- of the element 16, so that in one position of the element 14, the element 16 may freely move through the aperture 15, whereas, in another position of the element 14, the element 16 will be held against movement, in virtue of the impinging action betweenv certain walls. of the aperture 15 and the side edges of the element 16. The device em bodies co-acting members 19 and 20. The member 19 is carried by the element 14 and the member 20 is carried by the plate 13. As the element 14 is'moved on its pivot upwardly to a predetermined degree, the member 19 which is resilient, will frictionally engage the member 20 to sustain the element 14 in a position which will permit the element 16 to move freely through the aperture 15 in a downward direction. The element 16 is at all times permitted to have an upward movement and regardless ofany position the element 14 may be in. Moreover, except when the member 19 is in frictional engagement with the member 20, the I element 14 is influenced by the action of gravity and invariably assumes the position shown in Fig. 2 of the drawing, in

which position of the element 14, the element 16 is prevented from having downward movement, in other words, the relative positions the elements 16 and 14 assume, sets up the impinging action between these parts-*the cross sectional area in an oblique plane with respect to the side edges of the element 16 as distinguished from the cross sectional dimensions on a plane at right edges of the element 16 and smaller than the cross sectional dimensions of the element 16 taken on a plane which is oblique to the side edges of said element 16, thus permitting the free movement of the element 16 through the aperture 15 in the position of the element 14 shown in Fig. 3 of the drawing and preventing movement of the element 16 through the aperture 15 when the element 14 is in the position shown in Figs. 1 and 2 of the drawing. The element 14 is engageable by a pin 21 carried by the element 16 in the upward movement of said element, to cause the co-action of the members 19 and 20 to sustain the element 14 to permit the downward movement of the element 16 and consequently the closing of the lid. The element 16 is provided with a shoulder 22 formed by cutting away the element. In the downward movement of the element 16 the shoulder 22 engages the upper face of the element 14 to release it from its frictionally sustained position to the action of gravity substantially at the time the lid assumes a closed position in which condition it again permits of the upward movement of the lid.

From the foregoing it will be understood that the lid may be moved to various or different open positions and to the most minute degrees; that the lid will besustained and will be held against being closed except by firstmoving the lid until the pin 21 engages the element 14 to move the same to its non-impinging position, when the lid may be moved to a closed position. The element 14 is limited in its upward movement since the projection 14 of said element will engage the member 20 as shown in Fig. 3 of the drawing.

In the modified form of the invention shown in Fig. 5 of the drawing, the equivalent of the element 14 is shown as being of two parts, namely, the part 23 which is fixedly secured and the part 24 is pivoted as at 25 and this part is actuated after the fashion of the complete element 14 of the preferred form of the invention. It will therefore be understood that the only difference in the modification over the preferred form of the invention is that instead of using a one piece element 14, two parts will be used, the co-action of the parts 23 and 24 with the element 26, as in the modification will be identical as regards the result, as that produced by the elements 14 and 16 of the preferred form of the invention.

What is claimed as new is 1. In a device as characterized a pair of pivoted elements, one of said elements being frictionally controlled to permit the movement of the other of said elements relatively to the first element, and means for causing the said elements to interlock with each other to prevent the movement of the second element relatively to said first element.

2.
